3.6.34 CALCVV (Calculate using two User Variables)
The CALCVV instruction directly uses the contents of two user variables for an arithmetic operation, storing
the result in the first user variable. This eliminates the need for using the accumulator register and/or X
register for such purposes. The parameters of this command are the arithmetic function, the index of the
first user variable (0. . . 255) and the index of the second user variable (0. . . 255). This command is mainly
intended for use in standalone mode.
Related commands: CALCVA, CALCAV, CALCVX, CALCXV, CALCV.
Mnemonic: CALCVV <operation>, <var1>, <var2>
